The birth of Prince George has inspired the Queen to invite Carole and Michael Middleton to Sandringham so the future king can spend his first Christmas with both sets of grandparents, it emerged today.

In a break from tradition, the Duchess of Cambridge's parents have been asked to Her Majesty's Norfolk estate over the festive period.

Prince William spent last Christmas at the Middleton's mansion in Bucklebury, Berkshire, because his wife was pregnant.

Kate's sister Pippa may also be invited to Norfolk, where she would join all the senior royals including the Duke of Edinburgh, Prince Charles and the Duchess of Cornwall, Camilla.

The family event could also coincide with the Cambridges moving into their new 10-bedroom country bolthole in the grounds of Sandringham.
